Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flowchart of an implementation of a data matching method for a dynamic weighing system of a vehicle according to an embodiment of the present invention, which is detailed as follows:
s101, receiving image information of a plurality of detected vehicles, putting the image information of the plurality of detected vehicles into a first preset queue according to the receiving sequence, and aiming at any detected vehicle, forming an identification signal of the detected vehicle by the image information of the detected vehicle and the time T1 of receiving the image information in the first preset queue.
The method provided by the embodiment of the invention is applied to a vehicle weighing system as shown in fig. 2, the vehicle weighing system comprises an image acquisition module, a weighing module and a triggering module, the triggering module is respectively connected with the image acquisition module and the weighing module, when a vehicle to be measured arrives at the weighing module, the triggering module triggers the image acquisition module and the weighing module to be started simultaneously, the image acquisition module is used for acquiring the image information of the vehicle to be measured, and the weighing module is used for acquiring the weighing information of the vehicle to be measured.
Optionally, the image acquisition module may be one or more cameras erected on the road frame, the weighing module is a plurality of sensors arranged in the road surface and laid according to preset requirements, and the triggering module is a coil.
The image information of the detected vehicle comprises images of the vehicle, including but not limited to a head image, a tail image and a side image of the vehicle, and also comprises license plate information of the vehicle, including a license plate number and a license plate type, wherein the license plate type includes but not limited to a yellow plate, a blue plate and the like.
S102, receiving the weighing information of the plurality of detected vehicles, putting the weighing information of the plurality of detected vehicles into a second preset queue according to the receiving sequence, and aiming at any detected vehicle, forming a weighing signal of the detected vehicle by the weighing information of the detected vehicle and the time T2 of receiving the weighing information in the second queue.
S103, according to the time T1 and the time T2, the identification signals in the first preset queue and the weighing signals in the second preset queue are matched, and the identification signals and the weighing signals corresponding to each detected vehicle are obtained.
The triggering module triggers the image acquisition module and the weighing module to be started simultaneously, so that the weighing module acquires the weighing information of the vehicle to be measured, and the image acquisition module acquires the image information of the vehicle to be measured simultaneously.
However, since the weighing module is composed of weighing sensors laid on the road according to a preset rule, the weighing module can upload complete weighing information only when the vehicle completely leaves the weighing module.
Therefore, for the weighing information and the image information of the same vehicle under test, the time T1 at which the image information is received is earlier than the time T2 at which the weighing information is received, but the time interval between T1 and T2 is within the preset time range.
Based on this, optionally, for any identification signal S1 in the first preset queue, if there is a weighing signal C1 in the second preset queue, a time T2 corresponding to the weighing signal C1 is located after a time T1 corresponding to the identification signal S1, and a difference between the T2 and the T1 is greater than or equal to a first preset value and less than or equal to a second preset value, the identification signal S1 and the weighing signal C1 are matched as an identification signal and a weighing signal corresponding to a vehicle to be tested.
Optionally, after the identification signal S1 and the weighing signal C1 are matched to be the identification signal and the weighing signal corresponding to the vehicle to be tested, the identification signal S1 and the weighing signal C1 are stored in a preset storage space according to a preset format, the identification signal S1 is deleted from the first preset queue, and the weighing signal C1 is deleted from the second preset queue.
Optionally, with reference to fig. 2, the vehicle weighing system further includes an image auxiliary recognition module, the image auxiliary recognition module is connected to the trigger module, and the image auxiliary recognition module is configured to collect image information of a vehicle to be measured simultaneously with the image collection module when the vehicle to be measured reaches the weighing module, and record a time when the image information of the vehicle to be measured is obtained, and the method further includes:
aiming at any weighing signal in the second preset queue, if no identification signal matched with the weighing signal exists in the first queue, acquiring an identification signal matched with the weighing signal according to the time T2 corresponding to the weighing signal and the image information of the detected vehicle acquired by the image auxiliary identification module;
or, for any identification signal, judging whether the image information in the identification signal is complete according to a preset strategy, and if the image information is incomplete, acquiring the missing image information through an image identification algorithm according to the time T1 corresponding to the identification signal and the image information of the detected vehicle acquired by the image auxiliary identification module.
By the method, the conditions of image information loss and missing are processed, and the integrity of data is ensured.
Optionally, judging whether the two identification signals are repeated identification signals according to the image information in the identification signals and the time when the image information is received; if the two identification signals are repeated identification signals, one of the identification signals is deleted.
For example, the time interval between the two received image information is lower than a preset threshold, image recognition is performed according to the images in the image information, for example, whether the same detected vehicle is detected is judged according to the license plate number, if yes, the repeated identification signals are described, and one identification signal is deleted.
Optionally, the weighing information of the vehicle to be measured includes the weight of the vehicle to be measured, and after the vehicle weighing information is received, an embodiment of the present invention further provides a method for preprocessing the weighing information, including:
judging whether any weighing signal meets a preset rule or not; if yes, judging whether the weight of the detected vehicle is less than or equal to a preset weight, and if yes, deleting the weighing signal; or judging whether the weight of the detected vehicle is within a preset range, and if not, deleting the weighing signal.
And checking whether the weighing signal is legal or not by a protocol checking method, if so, rejecting some data with undersized weight, analyzing according to the weight data, and removing a normal weight data interval counted according to big data, namely abnormal weight data with an overlong or overlong weight value compared in the preset range.
In this way, the amount of computation for data matching is reduced.
Optionally, after the matching of the weighing signal and the identification signal is completed, the method further includes: acquiring the number of axles of the vehicle to be measured according to the weighing sensor signal corresponding to the vehicle to be measured; and judging whether the detected vehicle is overweight or not according to the number of axles of the detected vehicle and the weight of the detected vehicle and a preset strategy.
In the signals of the weighing sensors of the vehicle, a plurality of signals represent the number of axles of the vehicle to be measured, and the vehicles with two axles, four axles and the like can be intelligently identified in the mode.
The regulations on the management of the running roads of over-limit transport vehicles make clear regulations on over-limit transport vehicles, such as: the total weight of the two-axle truck exceeds 18000 kg; the total weight of the three-axle truck exceeds 25000 kilograms; the total mass of the train and goods of the three-axle train exceeds 27000 kilograms; the total mass of the four-axle truck exceeds 31000 kg; the total mass of the four-axle automobile train exceeds 36000 kg; the total mass of the five-axis automobile train exceeds 43000 kg; the total mass of the six-shaft and more than six-shaft automobile trains exceeds 49000 kg, wherein the driving shaft of the tractor is single-shaft, and the total mass of the automobile trains exceeds 46000 kg.
Therefore, whether the detected vehicle is overweight or not needs to simultaneously refer to two parameters of the number of axles and the weight of the detected vehicle. By the method, whether the vehicle is an overweight vehicle can be accurately judged.
According to the invention, when the vehicle reaches the weighing module, the weighing module and the image acquisition module are simultaneously triggered through the trigger module, and the weighing signal and the identification signal of the vehicle to be detected are matched by recording the moment of receiving the image information acquired by the image acquisition module and the moment of sending the weighing information by the weighing module, so that the matching precision is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
